Category:Security:SSA

Slackware has recently started to be inactive. At the same time, a number of security issues have been found in various components. This page aims at listing them in order to help everyone know which components have known vulnerabilities.

The list below is provided as-is. It is meant to be as good as possible but we can't guarantee anything. It is sorted by slackware categories: a/, ap/, d/, ...

A more comprehensive effort might appear at some point in the future (binary packages?) but this is currently only a list of packages and their CVEs when applicable and useful. In some cases, we consider pointing out a specific CVE is not useful because of the number of issues (i.e. get the last version; e.g. mozilla-*).

The CVEs are typically listed as follow: ${SUMMARY}

• Fix:
  • Fixed upstream on: ${DATE}
  • Available in version: ${UPSTREAM_VERSION_WITH_FIX} (-current ${VERSION_IN_CURRENT}; -stable: ${VERSION_IN_13_37})
  • Upstream commit: ${URL_TO_THE_SPECIFIC_FIX_COMMIT}

CVE-2011-2939 (DDoS, affected: current and stable)

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 (on cve.mitre.org).

• Fix:
  • Fixed upstream on: Tue, 9 Aug 2011
  • Available in version: 5.14.2 (-current: 5.14.0; -stable: 5.12.3)
  • Commit: http://perl5.git.perl.org/perl.git/commitdiff/e46d973584785af1f445c4dedbee4243419cb860#patch5

CVE-2011-4415 (DoS, affected : current, 13.37 and all before)

The ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, does not restrict the size of values of environment variables, which allows local users to cause a denial of service (memory consumption or NULL pointer dereference) via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, related to (1) the "len +=" statement and (2) the apr_pcalloc function call, a different vulnerability than CVE-2011-3607.

CVE-2011-3607 (OverflowGain privileges, affected : current, 13.37 and all before)

Integer overflow in the ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, allows local users to gain privileges via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, leading to a heap-based buffer overflow.

CVE-2011-3368 (affected : current, 13.37 and all before)

The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers via a malformed URI containing an initial @ (at sign) character.

proftpd

CVE-2011-4130 (Execute Code, affected : current, 13.37, and all before)

(proftpd bug tracker #3711)

Use-after-free vulnerability in the Response API in ProFTPD before 1.3.3g allows remote authenticated users to execute arbitrary code via vectors involving an error that occurs after an FTP data transfer.

php

CVE-2011-4885 CVE-2011-3379 (Denial Of Service, affected : current, 13.37 and all before )

PHP before 5.3.9 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.

libXfont

CVE-2011-2895 (Execute CodeOverflow, current, 13.37 and all before)

The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896.
