Summary

rpm security update

Details

The RPM Package Manager (RPM) is a powerful package management system capability as below

Security Fix(es):

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.(CVE-2026-103242)

A flaw was found in rpm. An attacker can supply a crafted manifest file that, when processed by a user or automation using rpm -q -p or similar manifest-processing flows, leads to arbitrary code execution. This occurs because manifest entries are unexpectedly macro-expanded before being opened, allowing embedded shell commands to run with the privileges of the rpm process. Successful exploitation can lead to a full compromise of confidentiality, integrity, and availability for the affected account.(CVE-2026-95519)
