1) Memory corruption

EUVDB-ID: #VU99782

Risk: Low

CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2005-1263

CWE-ID: CWE-119 - Memory corruption

Exploit availability: Yes

Description

The vulnerability allows a local user to execute arbitrary code.

The elf_core_dump function in binfmt_elf.c for Linux kernel 2.x.x to 2.2.27-rc2, 2.4.x to 2.4.31-pre1, and 2.6.x to 2.6.12-rc4 allows local users to execute arbitrary code via an ELF binary that, in certain conditions involving the create_elf_tables function, causes a negative length argument to pass a signed integer comparison, leading to a buffer overflow.

Mitigation

Install update from vendor's repository.
