Compress::Raw::Zlib module for Perl inflate() function buffer overflow
| perl-compressrawzlib-inflate-bo (51062) |  High Risk |
Description:
The Compress::Raw::Zlib module for Perl is vulnerable to a heap-based buffer overflow, caused by an off-by-one error in the inflate() function. By persuading a victim to open a .zip file containing a specially-crafted zlib-stream, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the affected application to crash.
