Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2014-5119)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Off-by-one error in the __gconv_translit_find function in gconv_trans.c in GNU C Library (aka glibc) allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via vectors related to the CHARSET environment variable and gconv transliteration modules.
2) Unchecked Return Value (CVE-ID: CVE-1999-0199)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
manual/search.texi in the GNU C Library (aka glibc) before 2.2 lacks a statement about the unspecified tdelete return value upon deletion of a tree's root, which might allow attackers to access a dangling pointer in an application whose developer was unaware of a documentation update from 1999.
