1) Code Injection

EUVDB-ID: #VU44428

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2011-3378

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

RPM 4.4.x through 4.9.x, probably before 4.9.1.2, allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via an rpm package with crafted headers and offsets that are not properly handled when a package is queried or installed, related to (1) the regionSwab function, (2) the headerLoad function, and (3) multiple functions in rpmio/rpmpgp.c.

Mitigation

Install update from vendor's website.
