Debian 11 DSA 752-1 Moderate: Gzip Local And Remote Threats Fix

Imran Ghory discovered a race condition in the permissions setting
code in gzip. When decompressing a file in a directory an
attacker has access to, gunzip could be tricked to set the file
permissions to a different file the user has permissions to.

CAN-2005-1228

Ulf Härnhammar discovered a path traversal vulnerability in
gunzip. When gunzip is used with the -N option an attacker could
this vulnerability to create files in an arbitrary directory with
the permissions of the user.

For the oldstable distribution (woody) these problems have been fixed in
version 1.3.2-3woody5.

For the stable distribution (sarge) these problems have been fixed in
version 1.3.5-10.

For the unstable distribution (sid) these problems have been fixed in
