CVE-2019-5052 4 Canonical, Debian, Libsdl and 1 more 5 Ubuntu Linux, Debian Linux, Sdl2 Image and 2 more 2024-11-21 6.8 MEDIUM 8.8 HIGH
An exploitable integer overflow vulnerability exists when loading a PCX file in SDL2_image 2.0.4. A specially crafted file can cause an integer overflow, resulting in too little memory being allocated, which can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.
CVE-2019-5051 4 Canonical, Debian, Libsdl and 1 more 5 Ubuntu Linux, Debian Linux, Sdl2 Image and 2 more 2024-11-21 6.8 MEDIUM 8.8 HIGH
An exploitable heap-based buffer overflow vulnerability exists when loading a PCX file in SDL2_image, version 2.0.4. A missing error handler can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.
CVE-2019-5018 2 Canonical, Sqlite 2 Ubuntu Linux, Sqlite 2024-11-21 6.8 MEDIUM 8.1 HIGH
An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0. A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote code execution. An attacker can send a malicious SQL command to trigger this vulnerability.
CVE-2019-3900 7 Canonical, Debian, Fedoraproject and 4 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2024-11-21 6.8 MEDIUM 7.7 HIGH
An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario.
CVE-2019-3887 4 Canonical, Fedoraproject, Linux and 1 more 11 Ubuntu Linux, Fedora, Linux Kernel and 8 more 2024-11-21 4.7 MEDIUM 5.6 MEDIUM
A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister (MSR) access with nested(=1) virtualization enabled. In that, L1 guest could access L0's APIC register values via L2 guest, when 'virtualize x2APIC mode' is enabled. A guest could use this flaw to potentially crash the host kernel resulting in DoS issue. Kernel versions from 4.16 and newer are vulnerable to this issue.
CVE-2019-3885 3 Canonical, Clusterlabs, Fedoraproject 3 Ubuntu Linux, Pacemaker, Fedora 2024-11-21 5.0 MEDIUM 3.3 LOW
A use-after-free flaw was found in pacemaker up to and including version 2.0.1 which could result in certain sensitive information to be leaked via the system logs.
CVE-2019-3882 6 Canonical, Debian, Fedoraproject and 3 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable.
CVE-2019-3878 4 Canonical, Fedoraproject, Mod Auth Mellon Project and 1 more 10 Ubuntu Linux, Fedora, Mod Auth Mellon and 7 more 2024-11-21 6.8 MEDIUM 8.1 HIGH
A vulnerability was found in mod_auth_mellon before v0.14.2. If Apache is configured as a reverse proxy and mod_auth_mellon is configured to only let through authenticated users (with the require valid-user directive), adding special HTTP headers that are normally used to start the special SAML ECP (non-browser based) can be used to bypass authentication.
CVE-2019-3877 4 Canonical, Fedoraproject, Mod Auth Mellon Project and 1 more 4 Ubuntu Linux, Fedora, Mod Auth Mellon and 1 more 2024-11-21 4.3 MEDIUM 5.8 MEDIUM
A vulnerability was found in mod_auth_mellon before v0.14.2. An open redirect in the logout URL allows requests with backslashes to pass through by assuming that it is a relative URL, while the browsers silently convert backslash characters into forward slashes treating them as an absolute URL. This mismatch allows an attacker to bypass the redirect URL validation logic in apr_uri_parse function.
CVE-2019-3874 5 Canonical, Debian, Linux and 2 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2024-11-21 3.3 LOW 6.5 MEDIUM
The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable.
CVE-2019-3846 7 Canonical, Debian, Fedoraproject and 4 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2024-11-21 8.3 HIGH 8.8 HIGH
A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network.
CVE-2019-3844 3 Canonical, Netapp, Systemd Project 7 Ubuntu Linux, Cn1610, Cn1610 Firmware and 4 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
It was discovered that a systemd service that uses DynamicUser property can get new privileges through the execution of SUID binaries, which would allow to create binaries owned by the service transient group with the setgid bit set. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the GID will be recycled.
CVE-2019-3843 4 Canonical, Fedoraproject, Netapp and 1 more 8 Ubuntu Linux, Fedora, Cn1610 and 5 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
It was discovered that a systemd service that uses DynamicUser property can create a SUID/SGID binary that would be allowed to run as the transient service UID/GID even after the service is terminated. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the UID/GID will be recycled.
CVE-2019-3839 6 Artifex, Canonical, Debian and 3 more 6 Ghostscript, Ubuntu Linux, Debian Linux and 3 more 2024-11-21 6.8 MEDIUM 7.8 HIGH
It was found that in ghostscript some privileged operators remained accessible from various places after the CVE-2019-6116 fix. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. Ghostscript versions before 9.27 are vulnerable.
CVE-2019-3832 3 Canonical, Debian, Libsndfile Project 3 Ubuntu Linux, Debian Linux, Libsndfile 2024-11-21 1.9 LOW 5.5 MEDIUM
It was discovered the fix for CVE-2018-19758 (libsndfile) was not complete and still allows a read beyond the limits of a buffer in wav_write_header() function in wav.c. A local attacker may use this flaw to make the application crash.
CVE-2019-3825 3 Canonical, Gnome, Redhat 3 Ubuntu Linux, Gnome Display Manager, Enterprise Linux 2024-11-21 6.9 MEDIUM 6.3 MEDIUM
A vulnerability was discovered in gdm before 3.31.4. When timed login is enabled in configuration, an attacker could bypass the lock screen by selecting the timed login user and waiting for the timer to expire, at which time they would gain access to the logged-in user's session.
CVE-2019-3824 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
A flaw was found in the way an LDAP search expression could crash the shared LDAP server process of a samba AD DC in samba before version 4.10. An authenticated user, having read permissions on the LDAP server, could use this flaw to cause denial of service.
CVE-2019-3823 5 Canonical, Debian, Haxx and 2 more 7 Ubuntu Linux, Debian Linux, Libcurl and 4 more 2024-11-21 5.0 MEDIUM 4.3 MEDIUM
libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.
CVE-2019-3822 7 Canonical, Debian, Haxx and 4 more 16 Ubuntu Linux, Debian Linux, Libcurl and 13 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2019-3820 3 Canonical, Gnome, Opensuse 3 Ubuntu Linux, Gnome-shell, Leap 2024-11-21 4.6 MEDIUM 4.3 MEDIUM
It was discovered that the gnome-shell lock screen since version 3.15.91 did not properly restrict all contextual actions. An attacker with physical access to a locked workstation could invoke certain keyboard shortcuts, and potentially other actions.
