Description:
Two vulnerabilities have been reported in libungif, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a user's system.
1) A NULL pointer dereferencing error can be exploited to crash an application that uses libungif via a specially crafted ".gif" file.
2) A boundary error can be exploited to cause out-of-bounds memory access, potentially allowing arbitrary code execution in an application that uses libungif via a specially crafted ".gif" file.
The vulnerabilities exist in "gifalloc.c", "dgif_lib.c" and "egif_lib.c".
The vulnerabilities have been reported in version 4.1.3. Prior versions may also be affected.
Note: All applications that use libungif are potentially affected by these vulnerabilities.
