CyberRota Analysis
AI-GeneratedA heap-based buffer overflow vulnerability exists in the RPM package manager, specifically in the handling of the RPMTAG_FILESIGNATURES field in crafted, unsigned RPM packages. This flaw allows an attacker to manipulate the allocation of a one-byte buffer, leading to potential arbitrary code execution through the use of tools like rpm2cpio, rpm2archive, and rpm -qlvp on untrusted packages. Organizations utilizing RPM for package management should prioritize patching this vulnerability to mitigate the risk of exploitation.
Original NVD Description
A heap-based buffer overflow flaw was found in rpm. RPMTAG_FILESIGNATURES in a crafted, unsigned RPM package's main header is declared with the wrong header type, causing hex2binv() to allocate a one-byte buffer and then write the tag's attacker-controlled, hex-decoded content — of attacker-chosen length — past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package.
