CVE-2011-2939 is a vulnerability of currently unknown severity. Off-by-one error in the decode_xs function in Unicode/Unicode.xs in the Encode module before 2.44, as used in Perl before 5.15.6, might allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Unicode string, which triggers a heap-based buffer overflow.. EPSS estimates a 2.65% chance of exploitation in the next 30 days.
