Debian: DSA-2844-1 Important: OpenSSL Vulnerabilities Addressed

CVE-2014-0978

It was discovered that user-supplied input used in the yyerror()
function in lib/cgraph/scan.l is not bound-checked before beeing
copied into an insufficiently sized memory buffer. A
context-dependent attacker could supply a specially crafted input
file containing a long line to cause a stack-based buffer overlow,
resulting in a denial of service (application crash) or potentially
allowing the execution of arbitrary code.

CVE-2014-1236

Sebastian Krahmer reported an overflow condition in the chkNum()
function in lib/cgraph/scan.l that is triggered as the used regular
expression accepts an arbitrary long digit list. With a specially
crafted input file, a context-dependent attacker can cause a
stack-based buffer overflow, resulting in a denial of service
(application crash) or potentially allowing the execution of
arbitrary code.

For the oldstable distribution (squeeze), these problems have been fixed in
version 2.26.3-5+squeeze2.
