bzip2 contains an off‑by‑one error in the bzip2recover utility. When processing a specially crafted file, the application performs an out‑of‑bounds write to a global buffer, resulting in memory corruption and a crash (denial of service).
This issue was fixed in bzip2 patch 35d122a3df8b0cc4082a4d89fdc6ee99f375fe67
A flaw was found in bzip2. The bzip2recover utility contains an off-by-one error that allows a local attacker to cause an out-of-bounds write to a global buffer by processing a specially crafted file. This memory corruption can lead to a crash, resulting in a Denial of Service (DoS).
Отчет
A Moderate impact denial of service flaw exists in the bzip2recover utility within bzip2. This vulnerability allows a local attacker to trigger an out-of-bounds write and crash the application by processing a specially crafted compressed file. Exploitation requires user interaction with a malicious file, limiting the attack vector to scenarios where untrusted bzip2 archives are processed by the recovery utility.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
