Common Vulnerabilities and Exposures assigned an identifier CVE-2009-3626 to the following vulnerability:
Perl 5.10.1 allows context-dependent attackers to cause a denial of service (application crash) via a UTF-8 character with a large, invalid codepoint, which is not properly handled during a regular-expression match.

Off-by-one error in the decodexs 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.
The bsdglob function in the File::Glob module for Perl before 5.14.2 allows context-dependent attackers to cause a denial of service (crash) via a glob expression with the GLOBALTDIRFUNC flag, which triggers an uninitialized pointer dereference.
A security flaw was found in the way Perl performed laundering of tainted data. A remote attacker could use this flaw to bypass Perl TAINT mode protection mechanism (leading to commands execution on dirty arguments or file system access via contaminated variables) via specially-crafted input provided to the web application / CGI script.

Perl 5.10.x allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an ability to inject arguments into a (1) getpeername, (2) readdir, (3) closedir, (4) getsockname, (5) rewinddir, (6) tell, or (7) telldir function call.
A denial of service flaw was found in the way Perl's rehashing code implementation (responsible for recalculation of hash keys and redistribution of hash content) used to react on certain user's input. If a Perl language based application accepted untrusted user input as hash keys, an attacker could use this flaw to cause the perl executable to consume excessive amount of memory (a denial of service via memory exhaustion).
