Background ========== GMime is a C/C++ library which may be used for the creation and parsing of messages using the Multipurpose Internet Mail Extension (MIME). Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/gmime < 2.4.15 >= 2.4.15 *>= 2.4.17 *>= 2.2.26 Description =========== GMime contains a buffer overflow flaw in the GMIME_UUENCODE_LEN macro in gmime/gmime-encodings.h. Impact ====== A context-dependent attacker could possibly execute arbitrary code or cause a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== GMime 2.4.x users on the PPC64 architecture should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/gmime-2.4.17" GMime 2.4.x users on other architectures should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/gmime-2.4.15" GMime 2.2.x users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/gmime-2.2.26" Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
