CVE-2021-20285 1 Upx 1 Upx 2025-04-11 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-2021-30500 3 Fedoraproject, Redhat, Upx 3 Fedora, Enterprise Linux, Upx 2025-04-11 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-2021-30501 3 Fedoraproject, Redhat, Upx 3 Fedora, Enterprise Linux, Upx 2025-04-11 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-2021-43311 1 Upx 1 Upx 2025-04-11 7.5 High
A heap-based buffer overflow 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:5382.
CVE-2021-43312 1 Upx 1 Upx 2025-04-11 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.
CVE-2021-43313 1 Upx 1 Upx 2025-04-11 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 PackLinuxElf32::invert_pt_dynamic at p_lx_elf.cpp:1688.
CVE-2021-43314 1 Upx 1 Upx 2025-04-11 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-2021-43315 1 Upx 1 Upx 2025-04-11 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:5349
CVE-2021-43316 1 Upx 1 Upx 2025-04-11 7.5 High
A heap-based buffer overflow was discovered in upx, during the generic pointer 'p' points to an inaccessible address in func get_le64().
CVE-2021-43317 1 Upx 1 Upx 2025-04-11 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 PackLinuxElf64::elf_lookup() at p_lx_elf.cpp:5404
CVE-2021-46179 1 Upx 1 Upx 2025-04-11 6.5 Medium
Reachable Assertion vulnerability in upx before 4.0.0 allows attackers to cause a denial of service via crafted file passed to the the readx function.
CVE-2023-23456 2 Fedoraproject, Upx 2 Fedora, Upx 2025-04-11 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-2023-23457 2 Fedoraproject, Upx 2 Fedora, Upx 2025-04-11 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-2019-14295 1 Upx 1 Upx 2025-04-11 N/A
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-2018-11243 1 Upx 1 Upx 2025-04-11 N/A
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.
