CVE-2015-8779 [CRITICAL] glibc: Unbounded stack allocation in catopen function
glibc: Unbounded stack allocation in catopen function
Stack-based buffer overflow in the catopen function in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long catalog name.
A stack based buffer overflow vulnerability was found in the catopen() function. An excessively long string passed to the function could cause it to crash or, potentially, execute arbitrary code.
Mitigation: Do not use applications which call catopen with unbounded strings. The catopen function is rarely used. Typical application usage involves passing a short, constant string to catopen, so most applications are not affect even if they call catopen.
