|---|---|---|---|---|---|
| CVE-2021-30500 | 3 Fedoraproject, Redhat, Upx | 3 Fedora, Enterprise Linux, Upx | 2025-04-11 | 6.8 MEDIUM | 7.8 HIGH |
| Null pointer dereference was found in upx PackLinuxElf::canUnpack() in p_lx_elf.cpp,in version UPX 4.0.0. That allow attackers to execute arbitrary code and cause a denial of service via a crafted file. | |||||
| CVE-2021-20285 | 1 Upx | 1 Upx | 2025-04-11 | 8.3 HIGH | 6.6 MEDIUM |
| A flaw was found in upx canPack in p_lx_elf.cpp in UPX 3.96. This flaw allows attackers to cause a denial of service (SEGV or buffer overflow and application crash) or possibly have unspecified other impacts via a crafted ELF. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2019-20051 | 2 Fedoraproject, Upx | 2 Fedora, Upx | 2025-04-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| A floating-point exception was discovered in PackLinuxElf::elf_hash in p_lx_elf.cpp in UPX 3.95. The vulnerability causes an application crash, which leads to denial of service. | |||||
| CVE-2021-43314 | 1 Upx | 1 Upx | 2025-04-11 | N/A | 7.5 HIGH |
| A heap-based buffer overflows was discovered in upx, during the generic pointer 'p' points to an inaccessible address in func get_le32(). The problem is essentially caused in PackLinuxElf32::elf_lookup() at p_lx_elf.cpp:5368 | |||||
| CVE-2023-23457 | 2 Fedoraproject, Upx | 2 Fedora, Upx | 2025-04-11 | N/A | 5.3 MEDIUM |
| A Segmentation fault was found in UPX in PackLinuxElf64::invert_pt_dynamic() in p_lx_elf.cpp. An attacker with a crafted input file allows invalid memory address access that could lead to a denial of service. | |||||
| CVE-2020-27787 | 1 Upx | 1 Upx | 2025-04-11 | N/A | 5.5 MEDIUM |
| A Segmentaation fault was found in UPX in invert_pt_dynamic() function in p_lx_elf.cpp. An attacker with a crafted input file allows invalid memory address access that could lead to a denial of service. | |||||
| CVE-2019-14295 | 1 Upx | 1 Upx | 2025-04-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| An Integer overflow in the getElfSections function in p_vmlinx.cpp in UPX 3.95 allows remote attackers to cause a denial of service (crash) via a skewed offset larger than the size of the PE section in a UPX packed executable, which triggers an allocation of excessive memory. | |||||
| CVE-2020-27800 | 1 Upx | 1 Upx | 2025-04-11 | N/A | 7.8 HIGH |
| A heap-based buffer over-read was discovered in the get_le32 function in bele.h in UPX 4.0.0 via a crafted Mach-O file. | |||||
| CVE-2023-23456 | 2 Fedoraproject, Upx | 2 Fedora, Upx | 2025-04-11 | N/A | 5.3 MEDIUM |
| A heap-based buffer overflow issue was discovered in UPX in PackTmt::pack() in p_tmt.cpp file. The flow allows an attacker to cause a denial of service (abort) via a crafted file. | |||||
| CVE-2020-27788 | 1 Upx | 1 Upx | 2025-04-11 | N/A | 5.5 MEDIUM |
| An out-of-bounds read access vulnerability was discovered in UPX in PackLinuxElf64::canPack() function of p_lx_elf.cpp file. An attacker with a crafted input file could trigger this issue that could cause a crash leading to a denial of service. | |||||
| CVE-2018-11243 | 1 Upx | 1 Upx | 2025-04-11 | 6.8 MEDIUM | 7.8 HIGH |
| PackLinuxElf64::unpack in p_lx_elf.cpp in UPX 3.95 allows remote attackers to cause a denial of service (double free), limit the ability of a malware scanner to operate on the entire original data, or possibly have unspecified other impact via a crafted file. | |||||
| CVE-2020-27799 | 1 Upx | 1 Upx | 2025-04-11 | N/A | 7.8 HIGH |
| A heap-based buffer over-read was discovered in the acc_ua_get_be32 function in miniacc.h in UPX 4.0.0 via a crafted Mach-O file. | |||||
| CVE-2021-30501 | 3 Fedoraproject, Redhat, Upx | 3 Fedora, Enterprise Linux, Upx | 2025-04-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| An assertion abort was found in upx MemBuffer::alloc() in mem.cpp, in version UPX 4.0.0. The flow allows attackers to cause a denial of service (abort) via a crafted file. | |||||
| CVE-2020-27802 | 1 Upx | 1 Upx | 2025-04-11 | N/A | 5.5 MEDIUM |
| An floating point exception was discovered in the elf_lookup function in p_lx_elf.cpp in UPX 4.0.0 via a crafted Mach-O file. | |||||
| CVE-2021-43312 | 1 Upx | 1 Upx | 2025-04-11 | N/A | 7.5 HIGH |
| A heap-based buffer overflow was discovered in upx, during the variable 'bucket' points to an inaccessible address. The issue is being triggered in the function PackLinuxElf64::invert_pt_dynamic at p_lx_elf.cpp:5239. | |||||
