MGASA-2015-0013 Updated glibc packages fix security vulnerabilities

The vfprintf function in stdio-common/vfprintf.c in GNU C Library aka glibc 2.5, 2.12, and probably other versions does not "properly restrict the use of" the alloca function when allocating the SPECS array, which allows context- dependent attackers to bypass the FORTIFYSOURCE format-string...

CVE-2012-3405: Undefined Security Weakness

The vfprintf function in stdio-common/vfprintf.c in libc in GNU C Library aka glibc 2.14 and other versions does not properly calculate a buffer length, which allows context-dependent attackers to bypass the FORTIFYSOURCE format-string protection mechanism and cause a denial of service segmentati...

CVE-2012-0864

Integer overflow in the vfprintf function in stdio-common/vfprintf.c in glibc 2.14 and other versions allows context-dependent attackers to bypass the FORTIFYSOURCE protection mechanism, conduct format string attacks, and write to arbitrary memory via a large number of arguments...
