Sourceware 17905 0 P2 RESOLVED catopen() Multiple unbounded stack allocations (CVE-2015-8779) 2020-04-06 14:54:24 UTC

Description Adam Mariš 2016-01-20 13:04:45 UTC 
A stack overflow vulnerability in the catopen function was found, causing applications which pass long strings to the catopen function to crash or, potentially execute arbitrary code.

Comment 1 Adam Mariš 2016-01-20 13:05:42 UTC 
Created glibc tracking bugs for this issue:

Affects: fedora-all [bug 1300314]
Comment 7 Martin Prpič 2016-07-07 07:57:13 UTC 
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.
