CVE-2021-44847 2 Fedoraproject, Toktok 2 Fedora, Toxcore 2024-11-21 7.5 HIGH 9.8 CRITICAL
A stack-based buffer overflow in handle_request function in DHT.c in toxcore 0.1.9 through 0.1.11 and 0.2.0 through 0.2.12 (caused by an improper length calculation during the handling of received network packets) allows remote attackers to crash the process or potentially execute arbitrary code via a network packet.
CVE-2021-44832 5 Apache, Cisco, Debian and 2 more 22 Log4j, Cloudcenter, Debian Linux and 19 more 2024-11-21 8.5 HIGH 6.6 MEDIUM
Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2.
CVE-2021-44733 5 Debian, Fedoraproject, Linux and 2 more 20 Debian Linux, Fedora, Linux Kernel and 17 more 2024-11-21 4.4 MEDIUM 7.0 HIGH
A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11. This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object.
CVE-2021-44731 3 Canonical, Debian, Fedoraproject 4 Snapd, Ubuntu Linux, Debian Linux and 1 more 2024-11-21 6.9 MEDIUM 7.8 HIGH
A race condition existed in the snapd 2.54.2 snap-confine binary when preparing a private mount namespace for a snap. This could allow a local attacker to gain root privileges by bind-mounting their own contents inside the snap's private mount namespace and causing snap-confine to execute arbitrary code and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1
CVE-2021-44730 3 Canonical, Debian, Fedoraproject 4 Snapd, Ubuntu Linux, Debian Linux and 1 more 2024-11-21 6.9 MEDIUM 7.8 HIGH
snapd 2.54.2 did not properly validate the location of the snap-confine binary. A local attacker who can hardlink this binary to another location to cause snap-confine to execute other arbitrary binaries and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1
CVE-2021-44686 2 Calibre-ebook, Fedoraproject 2 Calibre, Fedora 2024-11-21 5.0 MEDIUM 7.5 HIGH

CVE-2021-44648 3 Debian, Fedoraproject, Gnome 3 Debian Linux, Fedora, Gdkpixbuf 2024-11-21 6.8 MEDIUM 8.8 HIGH
GNOME gdk-pixbuf 2.42.6 is vulnerable to a heap-buffer overflow vulnerability when decoding the lzw compressed stream of image data in GIF files with lzw minimum code size equals to 12.
CVE-2021-44647 2 Fedoraproject, Lua 2 Fedora, Lua 2024-11-21 2.1 LOW 5.5 MEDIUM
Lua v5.4.3 and above are affected by SEGV by type confusion in funcnamefromcode function in ldebug.c which can cause a local denial of service.
CVE-2021-44537 2 Fedoraproject, Owncloud 2 Fedora, Owncloud Desktop Client 2024-11-21 6.8 MEDIUM 7.8 HIGH
ownCloud owncloud/client before 2.9.2 allows Resource Injection by a server into the desktop client via a URL, leading to remote code execution.
CVE-2021-44420 5 Canonical, Debian, Djangoproject and 2 more 5 Ubuntu Linux, Debian Linux, Django and 2 more 2024-11-21 7.5 HIGH 7.3 HIGH
In Django 2.2 before 2.2.25, 3.1 before 3.1.14, and 3.2 before 3.2.10, HTTP requests for URLs with trailing newlines could bypass upstream access control based on URL paths.
CVE-2021-44269 2 Fedoraproject, Wavpack 2 Fedora, Wavpack 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
An out of bounds read was found in Wavpack 5.4.0 in processing *.WAV files. This issue triggered in function WavpackPackSamples of file src/pack_utils.c, tainted variable cnt is too large, that makes pointer sptr read beyond heap bound.
CVE-2021-44225 2 Fedoraproject, Keepalived 2 Fedora, Keepalived 2024-11-21 5.5 MEDIUM 5.4 MEDIUM
In Keepalived through 2.2.4, the D-Bus policy does not sufficiently restrict the message destination, allowing any user to inspect and manipulate any property. This leads to access-control bypass in some situations in which an unrelated D-Bus system service has a settable (writable) property
CVE-2021-44224 6 Apache, Apple, Debian and 3 more 12 Http Server, Mac Os X, Macos and 9 more 2024-11-21 6.4 MEDIUM 8.2 HIGH
A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included).
CVE-2021-44143 3 Debian, Fedoraproject, Isync Project 3 Debian Linux, Fedora, Isync 2024-11-21 7.5 HIGH 9.8 CRITICAL
A flaw was found in mbsync in isync 1.4.0 through 1.4.3. Due to an unchecked condition, a malicious or compromised IMAP server could use a crafted mail message that lacks headers (i.e., one that starts with an empty line) to provoke a heap overflow, which could conceivably be exploited for remote code execution.
CVE-2021-44141 3 Fedoraproject, Redhat, Samba 3 Fedora, Storage, Samba 2024-11-21 3.5 LOW 4.3 MEDIUM
All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed.
CVE-2021-44025 3 Debian, Fedoraproject, Roundcube 3 Debian Linux, Fedora, Webmail 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
Roundcube before 1.3.17 and 1.4.x before 1.4.12 is prone to XSS in handling an attachment's filename extension when displaying a MIME type warning message.
CVE-2021-43976 5 Debian, Fedoraproject, Linux and 2 more 23 Debian Linux, Fedora, Linux Kernel and 20 more 2024-11-21 2.1 LOW 4.6 MEDIUM
In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).
CVE-2021-43975 4 Debian, Fedoraproject, Linux and 1 more 18 Debian Linux, Fedora, Linux Kernel and 15 more 2024-11-21 4.6 MEDIUM 6.7 MEDIUM
In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value.
CVE-2021-43860 4 Debian, Fedoraproject, Flatpak and 1 more 4 Debian Linux, Fedora, Flatpak and 1 more 2024-11-21 6.8 MEDIUM 8.2 HIGH
Flatpak is a Linux application sandboxing and distribution framework. Prior to versions 1.12.3 and 1.10.6, Flatpak doesn't properly validate that the permissions displayed to the user for an app at install time match the actual permissions granted to the app at runtime, in the case that there's a null byte in the metadata file of an app. Therefore apps can grant themselves permissions without the consent of the user. Flatpak shows permissions to the user during install by reading them from the "xa.metadata" key in the commit metadata. This cannot contain a null terminator, because it is an untrusted GVariant. Flatpak compares these permissions to the *actual* metadata, from the "metadata" file to ensure it wasn't lied to. However, the actual metadata contents are loaded in several places where they are read as simple C-style strings. That means that, if the metadata file includes a null terminator, only the content of the file from *before* the terminator gets compared to xa.metadata. Thus, any permissions that appear in the metadata file after a null terminator are applied at runtime but not shown to the user. So maliciously crafted apps can give themselves hidden permissions. Users who have Flatpaks installed from untrusted sources are at risk in case the Flatpak has a maliciously crafted metadata file, either initially or in an update. This issue is patched in versions 1.12.3 and 1.10.6. As a workaround, users can manually check the permissions of installed apps by checking the metadata file or the xa.metadata key on the commit metadata.
CVE-2021-43818 5 Debian, Fedoraproject, Lxml and 2 more 12 Debian Linux, Fedora, Lxml and 9 more 2024-11-21 6.8 MEDIUM 8.2 HIGH
lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, the HTML Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG files embedded using data URIs. Users that employ the HTML cleaner in a security relevant context should upgrade to lxml 4.6.5 to receive a patch. There are no known workarounds available.
