NONE Confidentiality impact
NONE Integrity impact
NONE Availability impact
PARTIAL Summary
The g_markup_escape_text function in the SILC protocol plug-in in libpurple 2.10.0 and earlier, as used in Pidgin and possibly other products, allows remote attackers to cause a denial of service (crash) via invalid UTF-8 sequences that trigger use of invalid pointers and an out-of-bounds read, related to interactions with certain versions of glib2.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Scientific Linux Local Security Checks NASL id SL_20111013_PIDGIN_ON_SL4_X.NASL description Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously. An input sanitization flaw was found in the way the Pidgin SILC (Secure Internet Live Conferencing) protocol plug-in escaped certain UTF-8 characters. A remote attacker could use this flaw to crash Pidgin via a specially crafted SILC message. (CVE-2011-3594) Multiple NULL pointer dereference flaws were found in the way the Pidgin Yahoo! Messenger Protocol plug-in handled malformed YMSG packets. A remote attacker could use these flaws to crash Pidgin via a specially crafted notification message. (CVE-2011-1091) All Pidgin users should upgrade to these updated packages, which contain backported patches to resolve these issues. Pidgin must be restarted for this update to take effect. last seen 2020-06-01 modified 2020-06-02 plugin id 61153 published 2012-08-01 reporter This script is Copyright (C) 2012-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/61153 title Scientific Linux Security Update : pidgin on SL4.x, SL5.x i386/x86_64 NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2011-1371.NASL description Updated pidgin packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.

When receiving various messages related to requesting or receiving authorization for adding a buddy to a buddy list, the oscar protocol plugin failed to validate that a piece of text was UTF-8. In some cases invalid UTF-8 data would lead to a crash (CVE-2011-4601). When receiving various incoming messages, the SILC protocol plugin failed to validate that a piece of text was UTF-8. In some cases invalid UTF-8 data would lead to a crash (CVE-2011-3594).
