Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2023:0088-1 advisory.

- 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-2021-20285)

- 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-2021-30500)

- 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-2021-30501)

- 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-2021-43311)

- 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-2021-43312)

- 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-2021-43313)

- 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-2021-43314)

- 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-2021-43315)

- A heap-based buffer overflow was discovered in upx, during the generic pointer 'p' points to an inaccessible address in func get_le64(). (CVE-2021-43316)

- 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-2021-43317)

- 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-2023-23456)

- 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-2023-23457)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected upx package.
