CVE-2008-5239: xine-lib 1.1.12, and other 1.1.15 and earlier versions, does not properly handle (a) negative and (b) zero val

Routine

MEDIUM 4.3DOWNGRADE

CVE-2008-5239 is a medium-severity flaw (CVSS 4.3) affecting xine-lib. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

xine-lib 1.1.12, and other 1.1.15 and earlier versions, does not properly handle (a) negative and (b) zero values during unspecified read function calls in input_file.c, input_net.c, input_smb.c, and input_http.c, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via vectors such as (1) a file or (2) an HTTP response, which triggers consequences such as out-of-bounds reads and heap-based buffer

xine xine-lib DOWNGRADE

Affected: 0.9.13 · 1 rc0a · 1 rc1 · 1 rc2 · 1 rc3 · 1 rc3a · 1 rc3b · 1 rc3c

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.9.13

1. Check installed version

apt-cache policy xine-lib || rpm -q xine-lib || xine-lib --version

2. No fixed release: DOWNGRADE to a release before 0.9.13 (Debian / Ubuntu)

apt-cache madison xine-lib sudo apt install xine-lib=<VERSION_BEFORE_0.9.13> sudo apt-mark hold xine-lib

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list xine-lib sudo dnf downgrade xine-lib-<VERSION_BEFORE_0.9.13> sudo dnf versionlock add xine-lib

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
